I have a KDS VS-7P monitor that was purchased 18 months ago, but I jus
started using it. Warranty has expired and shipping to KDS for repai
is way to expensive. Description of problem: Power led comes on. Bu

We have had a tv passed on to me and my wife via stepson. Its a rather
popular but cheap brand called Alba.
Anywho, after major redocorations and moving the tv from one place to

Model# VG191B
The problem with this monitor is that sometimes if you press the power
button, the unit will come on.  If its on and then press power to turn
it off, it will shut off but may not turn on if you hit the power

I wonder how many more years old glass picture tubes will still be made
for todays products . Its been amazing how long this old device has
lasted in production  .
I work in the salvage business for 6 years now and saw all regular

Posted this earlier! M # 24AF43. Plug in,
comes on, barely visible out of horizontal sync
pix (basically no video), no sound, channels do
change! Looks like the common "prima 20" T.V.

CTC 177 AG fully repaired the built-in tuner!
Reset EEPROM, all seems ok, but most stations,

Suddenly my DVD player (actually a combined DVD/VCR unit, the Philips
DVD757R) will no longer play DVDs. Just shows the 'Loading' message.
Occasionally spits out the CD, declaring it unplayable. This with
several known good DVDs.

has anyone come across a squealing chopper transformer in a p/s
is it caused by shorted output or a problem with the p/s itself?
its in a Panasonic TC-63R50N tv.
the p/s uses an STR51213 power ic which seems ok(not shorted).

thanks in advance

Sheesh. Weirdest thing just happened on a < 2 year old Philips
(RealFLat 27RF50S).  Was working.  Left room.  Come back 5 minutes
later and it's turned off.  Attempted power-up.  Made sound like it was
trying to cycle up - a clicking, maybe a couple times a second.  Tried

I have a heartbroken 3 year old because his remote control stopped
working for his dump truck and excavator.  I contacted New Bright and
they no longer have these and told me to try E-bay.  I have been
watching since October and haven't found anything.  Any suggestions?

I've got an Acer 7299SL monitor which is arcing in the CRT socket. Pulled
the focus leads from the socket and they're over 20KV, HV at the CRT is
around 24KV which seems pretty normal. Flyback is arcing slightly internally
so obviously shot. Anyone have a good used one or know where ...

I'm working on a 52" projection tv. Started out as a dead set. I replaced
the shorted HOT, and the standby B+ came up to 146 vdc. The chassis ran
for about 10 minutes, then I heard a pop, and it went back to a dead set
condition. The new Horiz Out Xistor probably shorted, but any ...

Whenever I turn on my TV set it works well for about 10 to 15 min but
after that a thin ray of light appears at the center with a black
background. It stays there for about 1 min or so then disappears. This
intermittent appearance has caused lot of trouble while watching the
